Since the install_icons target is only used to attach the 
POST_INSTALL_SCRIPT and work-around the current missing feature to 
rename files during installation I've partly solved the problem in 
CMake.  There is a new "INSTALL" command that serves as a placeholder 
for a future more powerful install specification interface.  For now it 
just has a simple "SCRIPT" option that allows one to specify a script to 
run at install time.  I've included the documentation of the command below.

This should allow you to convert the install_icons macro to not need to 
add a target at all.  The command will be included in the next KDE CMake 
release.

INSTALL
   Install rule specification interface command.

     INSTALL(SCRIPT <script1> [SCRIPT <script2> [...]])

   Specify rules to run at install time.  If SCRIPT is given the file
   named after it will be included in the install scripts.  Multiple
   SCRIPTs may be given within a single source directory and the scripts
   will be run in the order given.  The processing order of these scripts
   relative to install rules generated by INSTALL_TARGETS, INSTALL_FILES,
   and INSTALL_PROGRAMS commands is not specified.

   This command is a placeholder for a future larger interface.
